Introduction

Common causes of preterm birth may include cervical insufficiency, intrauterine infection, maternal chronic diseases, uterine malformations, and uterine fibroids. Uterine fibroids are benign tumors that can grow within the uterine wall or inside the uterine cavity. The presence of fibroids can lead to irregular contractions of the uterine wall, and if the fibroid is located within the uterine wall, it may contribute to preterm delivery.

Generally, factors that may lead to preterm birth include cervical insufficiency, intrauterine infection, maternal chronic diseases, uterine malformations, and uterine fibroids. The details are as follows:

1. Cervical Insufficiency

The cervix is the passage connecting the uterus and vagina, bearing the weight of the uterus during pregnancy. Cervical insufficiency may result from structural abnormalities of the cervix, previous cervical surgeries, or trauma. In such cases, the cervix cannot remain adequately closed, leading to premature exposure of the fetus to the external environment and increasing the risk of preterm birth.

2. Intrauterine Infection

Infections can alter the intrauterine environment, triggering inflammatory responses that may induce uterine contractions and cervical dilation. Additionally, infections can harm the fetus, further increasing the likelihood of preterm delivery.

3. Maternal Chronic Diseases

Chronic conditions such as hypertension, diabetes, and thyroid disorders can negatively affect the mother's health, impairing uterine blood flow and placental function, thereby increasing the risk of preterm birth.

4. Uterine Malformations

Uterine malformations can compromise the structure and function of the uterus, limiting the space available for fetal development. This may restrict fetal growth and contribute to preterm birth.

5. Uterine Fibroids

Uterine fibroids are benign tumors that can develop within the uterine wall or inside the uterine cavity. Their presence may cause irregular uterine contractions. If located within the uterine wall, fibroids may increase the risk of preterm birth.

Treatment for preterm birth should be evaluated and determined by a physician based on individual circumstances. Pregnant women should seek timely medical care and follow the guidance and treatment provided by healthcare professionals.

When should iron supplementation begin for premature low birth weight infants?

Preterm low-birth-weight infants should generally begin iron supplementation between the 4th and 8th week of life. Preterm infants refer to newborns born between 28 and 37 weeks of gestational age. These infants usually have low body weight and insufficient iron stores because iron transfer from mother to fetus primarily occurs during the late stages of pregnancy. Due to inadequate prenatal iron storage, most preterm infants require iron supplementation.

Aftereffects of a 7-month premature infant

Complications in infants born prematurely at seven months can affect the respiratory, digestive, and nervous systems. Premature infants have underdeveloped lungs; the use of mechanical ventilation and oxygen therapy may lead to complications such as airway softening and poor development of laryngeal cartilage. Their immature intestinal development can impair nutrient absorption later on. Additionally, incomplete development of brain nerves and blood vessels in preterm infants may result in neurological complications such as hydrocephalus and cerebral softening.

What causes premature birth in children?

Premature birth in infants may be caused by factors such as uterine malformations in the mother, maternal illness during pregnancy, or significant emotional fluctuations. Additionally, conditions during pregnancy such as placenta previa, placental abruption, or fetal abnormalities may also lead to preterm delivery. If a pregnant woman has unhealthy lifestyle habits or experiences abdominal trauma or impact, this could also trigger premature birth.

Why do pregnant women experience preterm labor?

In general, preterm birth refers to the delivery of an infant before 37 weeks of gestation and may be caused by factors such as unhealthy lifestyle habits, cervical insufficiency, multiple pregnancies, premature rupture of membranes, or hypertension. If a pregnant woman shows signs of preterm labor, it is recommended to seek medical attention promptly and, under a doctor's guidance, receive treatment with medications such as dexamethasone injection or betamethasone injection.

How long after birth does a premature infant pass the critical period?

If a premature infant is born close to 37 weeks of gestation, has a relatively high birth weight, and shows normal body temperature, respiration, nutrition, and no abnormal symptoms, it indicates that the critical period has passed. However, if the gestational age is smaller, organ systems and the nervous system are generally underdeveloped, and the critical period may last longer. Once all vital signs become stable, the baby's weight reaches over 4 catties (approximately 2 kg), and there are no abnormal symptoms, it suggests that the infant has passed the critical stage.

Can lying down more in the late stages of pregnancy prevent preterm birth? Can increased rest during late pregnancy help prevent premature delivery?

In late pregnancy, lying down more can help prevent preterm labor. For preterm labor caused by excessive fatigue, overactivity, sexual intercourse in late pregnancy, or cervical relaxation, bed rest is recommended to support fetal preservation. This helps reduce cervical tension and the stress on the cervix, thereby maintaining fetal stability in the uterus. Once effective fetal protection has been achieved, moderate physical activity is advised to avoid triggering or worsening bodily edema.

Is preterm birth calculated based on actual birth date or full-term gestation?

Preterm birth is generally determined based on whether the fetus has reached full term. The standard for full-term pregnancy in pregnant women is calculated from the first day of the last menstrual period, with each 7-day period counting as one gestational week. A pregnancy reaching 37 weeks is considered full term, 40 weeks corresponds to the expected due date, and delivery beyond 42 weeks is classified as post-term pregnancy. Clinically, infants born alive between 28 and 37 weeks of gestation are defined as preterm infants. Therefore, preterm birth is defined relative to full-term pregnancy.

What are the most common causes of inducing preterm labor?

There is usually no single most common cause of preterm labor. Factors that may induce preterm labor include excessive uterine distension, intrauterine infection, and pregnancy complications. In addition to the above-mentioned causes, preterm labor may also be associated with uterine malformation, placental abruption, and placenta previa. It is important to take preventive measures during pregnancy, follow medical advice to regularly attend prenatal checkups at the hospital, and closely monitor both fetal and maternal health.
